Bonehead, a Sunday ago we had about a foot of the wettest, heaviest snow we've had this season. It was mostly gone two days later. I had hoped to begin this project a little earlier, but the soil's still got enough moisture in it to make this go pretty smoothly.
We've done a lot of digging around our place and the soils we're working in now are some of the best we've got (too bad there isn't more of that right around the house)--pretty loamy. There is a LOT of seeps and clays around these hills. In fact one of my next projects is putting in some subsurface drain pipe to help the water move off a little more quickly.
By the way, great looking dog you've got there!
